Ninja Gaiden III: The Ancient Ship of Doom WII comments

Join master ninja Ryu Hayabusa,
last member of the famous Dragon Clan, in the third and final chapter of the
legendary Ninja Gaiden saga. Ryu is framed for FBI agent Irene Lew’s murder,
and it’s up to him to clear his name. Defeating superior life-forms created
out of "life energy" called BIO-NOIDs and avoiding enemy ambushes are among
the many obstacles which Ryu faces in this unpredictable adventure of mystery,
deceit and destruction. Noticeable changes to the game-play mechanics include
Ryu’s ability to grab on to horizontal surfaces, his reduced falling speed and
altered jumping maneuvers, and visible power-ups. Help Ryu defeat the forces
of evil once more and discover the real culprit behind Irene’s death as one of
the most loved trilogies in video-game history comes to a close.
